A pro team is a team with at least one licensed captain. It doesn't mean they are good or bad. I could get my license and I would be considered a "pro", but I'd still be just an average fisherman I believe the old rule for what a "pro" is was someone was a guide as well.
In the new forma there is "open" and "pro/am". Anyone can enter either division, although I hope next year they make the open division amateurs only.
